At 800 AM AST (1200 UTC), the eye of Hurricane Beryl was located near latitude 10.6 North, longitude 53.9 West. Beryl is moving toward the west near 21 mph (33 km/h). A continued quick westward to west-northwestward motion is expected during the next few days.
On the forecast track, the center of Beryl is expected to move across the Windward Islands early on Monday and across the southeastern Caribbean Sea Monday night and Tuesday. Aircraft data indicate that the maximum sustained winds have increased to near 115 mph (185 km/h) with higher gusts, making Beryl a very dangerous category 3 hurricane. Continued rapid strengthening is forecast over the next day or so, and Beryl is expected to become an extremely dangerous category 4 hurricane before it reaches the Windward Islands.
Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km).
The minimum central pressure based on data from the Air Force Hurricane Hunters is 968 mb (28.58 inches).
HAZARDS AFFECTING LAND
Key messages for Beryl can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.
WIND:
Hurricane conditions are expected in the hurricane warning area beginning early on Monday. Devastating wind damage is expected where the eyewall of Beryl moves through portions of the Windward Islands.
Tropical storm conditions are expected in the tropical storm warning area starting late tonight, making outside preparations difficult or dangerous. Tropical storm conditions are possible within the watch area starting late tonight. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater.
STORM SURGE:
A life-threatening storm surge will raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore flow near where Beryl makes landfall in the hurricane warning area. Near the coast, the surge will be accompanied by large and destructive waves.
RAINFALL:
Hurricane Beryl is expected to produce rainfall totals of 3 to 6 inches across Barbados and the Windward Islands tonight and Monday. This rainfall may cause flash flooding in vulnerable areas. For a complete depiction of forecast rainfall and flash flooding associated with Hurricane Beryl, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at2.shtml?rainqpf
SURF:
Large swells generated by Beryl are expected across Windward and southern Leeward Islands during the next couple of days. These swells are expected to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
